Title: Method and device for graphics mapping of a surface onto a two dimensional image
Inventor: DIJKSTRA HENDRIK
IPC: G06T15/10
Filed: 1997-04-28
Granted: 1999-10-11
Abstract: A series of point on a surface is projected onto pixel of an image along a projection axis. Furthermore, texture coordinates are allocated to the points as follows. First a normalized coordinate which is ratios of the texture coordinate to a depth of point along the projection axis is determined by linear interpolation. Displacement of the pixel is determined relative to a line in the image onto which a part of the surface, which has a constant depth in the projection direction, is projected. Subsequently, an interpolation function is calculated which interpolates the depth as a function of the displacement. The texture coordinate is determined by multiplication of the normalized coordinate by the depth. The image contribution by the point to an image content of the pixel is determined on the basis of the texture coordinate.

Title: Method for forming optical glass
Inventor: NAKAHARA MUNEO
IPC: C03B19/02
Filed: 1997-07-03
Granted: 2001-06-16
Abstract: The subject invention relates to a method for forming optical glass. The tip of the orifice in the outlet pipe is configured as an expanding cone and the opening of the tip is in immediate contact or immersed under the surface of the molten glass, such that the divitrification of glass or the generation of heterogeneous layer caused by the evaporation from the glass surface could be avoided. Furthermore, the guiding cast die of the mold is formed with a near parabolic taper surface toward the flowing direction, such that the flow of the glass is made smooth and the devitrification due to the dragging of the glass can be avoided. Moreover, the surface of the molten glass can be air-cooled to inhibit devitrification in the glass. High quality glass, including the thick optical glass pane easily susceptible to devitrification, which cannot be formed by conventional process, can be easily obtained by the method of the present invention.
Patent TW-367369-B (TW)
Title: Method for recovering cobalt/manganese/bromine values from residue containing used catalyst
Inventor: FEITLER DAVID
IPC: C07C51/265
Filed: 1997-07-08
Granted: 1999-08-21
Abstract: A process for recovering valuable components of a residue from a stream of used catalyst, discharged from a plant for the liquid-phase, homogeneously catalyzed oxidation of alkylaromatic compounds under pressure, to produce polycarboxylic aromatic acids. The residue containing mainly cobalt (Co) and manganese (Mn) compounds is injected into a molten metal bath in combination with enough oxygen gas to convert essentially all carbon in the residue mainly to CO. The residue may also be sludge from a pond in which the residue is stored. The Co content of the molten metal is determined by how much of the Mn in the residue is to be rejected from the molten metal. The Mn rejected is distributed between a slag overlying the molten metal and the effluent which leaves the bath. In the slag, the Mn is trapped as manganese oxide (MnO); in the effluent Mn leaves as manganese dibromide (MnBr2). The alloy recovered is atomized to form a powder metal which is then reacted with acetic acid and hydrogen bromide to form the corresponding salts. Mn and bromine (Br) values from the slag and from the effluent are also recovered. Substantially pure Co may be recovered and exported, particularly if earthy residue from a sludge pond is processed to benefit the environment.
Patent TW-591014-B (TW)
Title: Preparation of lactams from aliphatic alpha,omega-dinitriles
Inventor: DI COSIMO ROBERT
IPC: C07D211/76
Filed: 1997-09-11
Granted: 2004-06-11
Abstract: A process for the preparation of five-membered or six-membered ring lactams from aliphatic alpha,omega-dinitriles has been developed. In the process an aliphatic alpha,omega-dinitrile is first converted to an ammonium salt of an omega-nitrile-carboxylic acid in aqueous solution using a catalyst having an aliphatic nitrilase (EC 3.5.5.7) activity, or a combination of nitrile hydratase (EC 4.2.1.84) and amidase (EC 3.5.1.4) activities. The ammonium salt of the omega-nitrilecarboxylic acid is then converted directly to the corresponding lactam by hydrogenation in aqueous solution, without isolation of the intermediate omega-nitrilecarboxylic acid or omega-aminocarboxylic acid. When the aliphatic alpha,omega-dinitrile is also unsymmetrically substituted at the alpha-carbon atom, the nitrilase produces the omega-nitrilecarboxylic acid ammonium salt resulting from hydrolysis of the omega-nitrile group with greater than 98% regioselectivity, thereby producing only one of the two possible lactam products during the subsequent hydrogenation. A heat-treatment process to select for desirable regioselective nitrilase or nitrile hydratase activities while destroying undesirable activities is also provided.

Title: Memory redundant circuitry for high-density memory
Inventor: YANG NIAN-JAU
IPC: H01L27/112
Filed: 1998-08-07
Granted: 2001-05-01
Abstract: This invention is about a redundant device structure that is suitable for high-density integrated circuit memory, such as mask read only memory having relatively small configuration of two transistor redundant cells. Module with column and row failures can be repaired by using the redundant device structure of this invention. The redundant device structure can be fabricated by using the fabricating process of single metal, single polysilicon mask read only memory. The redundant cell is mainly composed of a diffusion word line and a redundant word line. This redundant word line is used to replace one word line of the word line set and is far away from the diffusion word line. The first and the second diffusion regions are set in between the diffusion word line and the redundant word line. A channel region is set in between the first and the second diffusion regions. The third diffusion region is adjacent to the redundant word line and is opposite to the second diffusion region. Therefore, the second hidden diffusion region can be treated as a source end and the third hidden diffusion region can be treated as a drain end such that the redundant word line can be treated as a gate transistor. A floating gate is laid out at the hidden diffusion word line and, is expanded to the redundant word line which is in between the hidden diffusion word line and the periphery of the first hidden diffusion region, and the channel region that is in between the first and the second hidden diffusion regions. The first contact window is set in between the first hidden diffusion region and the first bit line of the bit-line set. The second contact window is set in between the third hidden diffusion region and the second bit line of the bit-line set.

Title: Stage apparatus, scanning exposure apparatus and method and the device produced by the way
Inventor: NISHI KENJI
IPC: H01L21/68
Filed: 1998-09-19
Granted: 2000-10-11
Abstract: The invention uses the interferometer 76Y to measure directly the position of the stage WST along Y axis, and uses the measured value of the position of the stage WST calculated by the first interferometer 76X1 and the third interferometer 76X2 from different directions to calculate the position of the stage WST along X axis. Comparing to the previous rectangular stage, it is miniaturized and lighter due to the invention which makes the stage WST in triangular shape by configuring the first to the third reflective faces, 60a, 60b, 60c to be in triangular shape. Moreover, in the situation that the patterns of the mask is written in turn to the multiple areas S1 and S2, the throughput is improved by processing pre-scan of the photographing S2 and the stepping movement from stepping to photographing S2.
